Multiple times now I have left the game to come back to my quest line only saved multiple quests behind, including after defeating bosses. This has led to me repeating several bosses in the game, and multiple quests. It also affects secondary quests. it appears to set back by over 20 to 30 minutes of progress every time.
I am using the games menu to exit diablo after being in a main town.
For example my most recent issue was when fighting the witch for the quest line “Witch of the Wastes”
After defeating her and returning to town, I logged out last night for the night. Today after my appointments I logged in and all progress reverted back to before searching for the witch.
This has happened 2 other times for me. I also loose items I received in this period of time lost.
if there is anything missing here, please let me know what info you need from me on this and I can fill it in with the best of my knowledge.
edit Also when clicking to speak with someone for the quest line, the text is greyed out like I have already done the talking for the quest
